About 4-Methylphenylhydrazinehydrochloride

4-Methylphenylhydrazinehydrochloride (CAS Number: 637-60-5) is a hydrazine-containing compound used as a versatile nitrogen nucleophile featuring a Benzene ring. ChemContract Research supplies this simple-complexity compound in high purity from our Huntington Beach, California facility, ensuring consistent quality and reliable domestic delivery throughout the United States. Supplied as the hydrochloride salt form for enhanced stability and handling.

The N–N bond in hydrazines provides unique reactivity for heterocycle formation and is a key motif in several FDA-approved drugs including celecoxib and crizotinib analogs. Hydrochloride is the most common salt form for basic drug substances — approximately half of all salt-form drugs on the market are HCl salts, valued for their crystallinity and aqueous solubility.

Primary applications include synthesis of pyrazole and pyridazine heterocycles from 1,3-diketones and improved handling characteristics versus the free base form. This compound serves researchers and manufacturers across the pharmaceutical, agrochemical, fine chemical sectors. Whether you require 4-Methylphenylhydrazinehydrochloride for early-stage research, process development, or commercial-scale production, ChemContract Research offers flexible ordering from milligram to multi-kilogram quantities with custom synthesis options and full batch documentation including Certificates of Analysis (CoA) and Safety Data Sheets.
