Here is a detailed product description for  (4-Fluoro-3,5-dimethylphenyl)hydrazine hydrochloride , incorporating its chemical properties, potential uses, handling, and key identifiers:

Product Name: (4-Fluoro-3,5-dimethylphenyl)hydrazine hydrochloride

Alternative Name(s):

1-(4-Fluoro-3,5-dimethylphenyl)hydrazine hydrochloride; Hydrazine, (4-fluoro-3,5-dimethylphenyl)-, hydrochloride (1:1)

CAS Registry Number:   133263-91-1  (Note: The number "2212021-40-2" in your query is likely a supplier catalog number or internal code,  NOT  the standard CAS RN. The confirmed CAS RN for this compound is 133263-91-1).

Molecular Formula:  C₈H₁₁FN₂•HCl / C₈H₁₂ClFN₂

Molecular Weight:  189.64 g/mol (C₈H₁₁FN₂•HCl)

Solubility:  Generally soluble in water and polar organic solvents (e.g., methanol, ethanol, DMSO), often with some warming. Less soluble or insoluble in non-polar solvents (e.g., hexane, toluene).

Melting Point/Decomposition:  Hydrazine hydrochlorides often decompose before melting sharply. Expect decomposition typically in the range of approximately  200-250 °C , although this can vary and precise decomposition points are less commonly reported than for stable melting compounds. The compound is sensitive to heat.

Storage Conditions:

Store at 2-8°C (refrigerated) or -20°C for long-term stability.

Protect from light (light-sensitive).

Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation and moisture absorption.

Store in a cool, dry, well-ventilated place away from incompatible materials.

Stability:  Sensitive to air (oxygen), moisture, heat, and light. Can oxidize over time, potentially leading to darkening. Use promptly after opening.

Chemical Structure & Properties

Core Structure:  Features a phenyl ring substituted with:

A fluorine atom at the  para  position (position 4).

Methyl groups at both  meta  positions (positions 3 and 5).

A hydrazine group (-NH-NH₂) attached directly to the ring carbon at position 1.

Form:  Supplied as the  hydrochloride salt .

Advantages:  The salt form generally improves stability (reducing oxidation susceptibility compared to the free base), crystallinity, and handling characteristics. It also increases water solubility.

Reactivity:  The hydrochloride salt retains the characteristic reactivity of the hydrazine functional group.

Key Reactivity & Functional Group

Hydrazine Group (-NH-NH₂•HCl):  This is the defining and most reactive functional group.

Nucleophile:  Can act as a nucleophile, attacking electrophiles like carbonyls (aldehydes, ketones – forming hydrazones), isocyanates, activated halides, epoxides, etc.

Coupling Agent:  Used in diazotization reactions (forming diazonium salts upon treatment with nitrous acid), which are key intermediates for azo coupling (forming azo dyes) or Sandmeyer-type reactions.

Building Block:  Fundamental synthon for constructing heterocycles like pyrazoles, pyrazolines, indazoles, triazoles, and many other nitrogen-containing scaffolds via condensation or cyclization reactions.

Potential Applications

(Primary use is as a chemical building block/synthetic intermediate)

Pharmaceutical & Agrochemical Synthesis:  Key intermediate for synthesizing biologically active molecules, especially heterocyclic compounds (e.g., pyrazoles, triazoles, indazoles) with potential applications as drug candidates (e.g., enzyme inhibitors, receptor modulators) or agrochemicals (pesticides, herbicides).

Material Science:  Building block for specialty polymers, ligands for catalysts, or functional materials where the specific substitution pattern (fluoro, dimethyl) imparts desired properties.

Dye & Pigment Chemistry:  Intermediate for synthesizing azo dyes and pigments via diazotization and coupling reactions.

Organic Synthesis Research:  Versatile reagent for constructing complex nitrogen-containing molecules and exploring novel synthetic methodologies.

Safety & Handling (GHS Pictograms & Statements are illustrative - consult actual SDS)
