Product Overview

Overview

Indazole-3-carboxylic Acid (CAS No. 4498-67-3), also known as 1H-Indazole-3-carboxylic Acid, is a high-purity fine chemical and core pharmaceutical intermediate widely applied in modern organic synthesis, pharmaceutical research and biochemical industry. Supplied by Guangzhou Chunqiao Chemical Co., Ltd., this product features stable chemical properties, high purity consistency and excellent batch stability, serving as a key raw material for the synthesis of various high-value pharmaceutical derivatives and bioactive compounds. The product presents a standard light yellow crystalline powder appearance with uniform color, no color gradient, no impurities and no agglomeration, meeting international industrial and laboratory-grade application standards.

Basic Chemical Specifications

This compound has a molecular formula of C₈H₆N₂O₂ and a molecular weight of 162.15 g/mol, with accurate molecular structure and stable molecular activity. It owns fixed and reliable physical and chemical indicators: the melting point ranges from 266℃ to 270℃ (decomposition state), the boiling point is 443.7℃ under standard atmospheric pressure, the flash point is 222.2℃, and the density is 1.506 g/cm³. With extremely low vapor pressure (1.18E-08mmHg at 25℃), it has excellent storage stability and is not easy to volatilize or deteriorate under conventional room temperature environment. The product has a refractive index of 1.743 and a pKa value of 3.03±0.10, showing mild acidic characteristics, which is convenient for targeted chemical modification and derivative synthesis in organic reactions.

Product Appearance & Quality Characteristics

Our Indazole-3-carboxylic Acid strictly adopts refined purification technology, with a mainstream appearance of uniform light yellow powder. Compared with low-grade products on the market, our goods eliminate color difference, fading and mixed color phenomena, with fine and uniform powder texture, good fluidity and no abnormal particle impurities. The factory adopts standardized purification and screening processes to control product purity stably above 99%, with low moisture content and low impurity residue. Each batch of products undergoes strict QC inspection to ensure consistent quality parameters, stable chemical activity and high reaction activity, which can fully meet the rigorous experimental requirements of laboratory research and large-scale industrial synthesis production.

Core Application Fields

As a crucial heterocyclic aromatic carboxylic acid intermediate, Indazole-3-carboxylic Acid has irreplaceable application value in pharmaceutical synthesis and fine chemical industry. Firstly, it is widely used in the research and development and production of bioactive drugs. Its derivatives have significant pharmacological activities, covering , anti-inflammatory, anti-arthritis, gastric disease treatment , and are key raw materials for the synthesis of CRAC channel blockers. Secondly, it is an important building block for organic synthesis, commonly used for the preparation of indazole amide compounds and various high-purity heterocyclic chemical products, and is widely used in chemical customization and new material research.

In addition, the product is applicable to biochemical research, medical intermediate customization, laboratory formula development and other scenarios, supporting small-batch sample testing and large-batch industrial mass production. Its stable chemical structure ensures high synthesis yield and low by-product rate in the reaction process, effectively reducing the production cost and experimental error for customers, so it is deeply favored by pharmaceutical factories, chemical research institutions and new material enterprises all over the world.
