2-Chlorobenzaldehyde is a halogenated aromatic aldehyde supplied as a colorless to pale yellow clear liquid. The combination of an ortho-positioned chlorine atom and a reactive formyl group makes it a widely used building block in pharmaceutical, agrochemical, dye and heterocyclic chemistry. Dideu Group supplies this material from 1 kg trial quantities up to 200 kg drum-scale industrial volumes.

Product Description

2-Chlorobenzaldehyde (CAS 89-98-5) is an ortho-substituted chlorinated benzaldehyde with the molecular formula C7H5ClO and a molecular weight of 140.57 g/mol. It is supplied as a colorless to pale yellow clear liquid with a characteristic aldehyde odour, at a minimum assay of 99.0% by gas chromatography. The material melts at 9-11 C and boils at 209-215 C under atmospheric pressure, and is only slightly soluble in water while being freely soluble in common organic solvents such as ethanol, diethyl ether and acetone.

The value of this intermediate lies in its dual functionality. The formyl group reacts readily in aldol and Knoevenagel condensations, oxime and hydrazone formation, reductive amination and cyanohydrin chemistry, while the ortho chlorine provides a handle for nucleophilic aromatic substitution and for transition-metal catalysed coupling. This makes 2-chlorobenzaldehyde a common entry point to isoxazoles, quinazolines, dihydropyrimidines, benzoxazepines and a range of Schiff base ligands used in medicinal chemistry programmes.

Dideu Group supplies 2-chlorobenzaldehyde to formulators, CDMO and API manufacturers, agrochemical synthesis houses, dye producers and academic research groups. Material is packed in HDPE drums for industrial volumes and in sealed bottles for evaluation and laboratory quantities. Each batch is accompanied by a Certificate of Analysis, and buyers can request the specification sheet, the safety data sheet and the production route summary before placing an order. The minimum order quantity is 1 kg, and dispatch is normally arranged within 2 weeks after order confirmation.

Applications

Pharmaceutical Intermediates. 2-Chlorobenzaldehyde is a key precursor in the manufacture of isoxazolyl penicillins such as cloxacillin, where it provides the substituted aromatic ring of the side chain. It is also used to prepare ortho-chlorobenzaldehyde oxime and related intermediates for antibacterial and anti-inflammatory active pharmaceutical ingredients.

Agrochemical Intermediates. The compound serves as a starting material in the synthesis of acaricides and other crop protection actives, and is used in routes to hydrazine- and hydrazide-derived insecticide and acaricide structures.

Dyes and Pigments. It is employed as an intermediate in triphenylmethane and related dye chemistry, where the ortho-chloro substituent modifies the colour properties and the fastness of the finished dyestuff.

Fine Organic Synthesis. As a bifunctional aromatic aldehyde it is used in multicomponent reactions, heterocycle assembly, Schiff base and metal complex synthesis, and as a substrate in catalytic and mechanochemical methodology development.

Analytical Chemistry. 2-Chlorobenzaldehyde is used as a derivatising agent in liquid chromatography tandem mass spectrometry methods, for example in the quantification of nitrofuran metabolite residues in food and aquatic products, and as a reference standard precursor in method development laboratories.

Surface Finishing. Chlorinated benzaldehyde derivatives are used in electroplating bath formulations as brightening and levelling components for metal deposition processes.

FAQ

1. What is the minimum order quantity?

The minimum order quantity for 2-chlorobenzaldehyde is 1 kg. Smaller evaluation quantities in sealed bottles and larger industrial quantities in 25 kg or 200 kg HDPE drums are both available, so a single supplier can cover laboratory, pilot and commercial scale.

2. What is the lead time?

Orders are normally arranged for dispatch within 2 weeks after order confirmation. For recurring requirements we can reserve a fixed production slot so that the delivery date is agreed in advance.

3. What packaging options do you offer?

Standard packaging is 25 kg and 200 kg HDPE drums for industrial volumes, 1000 kg IBC containers for bulk orders, and sealed glass or aluminium bottles in 100 g, 500 g and 1 kg sizes for laboratory use. All containers are sealed and labelled with the batch number.

4. What payment terms do you accept?

We accept payment by T/T and by L/C. The exact terms, including the deposit arrangement and the currency of settlement, are confirmed in the proforma invoice for each order.

5. Do you provide COA and technical documents?

Yes. Dideu Group supplies a Certificate of Analysis for every batch, together with the technical data sheet and the safety data sheet. Documents can be issued for review before the order is confirmed, and the COA is shipped with the goods.
