About Phenazo Pyridine Hcl

Phenazo Pyridine Hcl (CAS Number: 136-40-3) is a heterocycle-containing compound — the dominant scaffold class in approved pharmaceuticals featuring a Pyridine 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.

Heterocyclic rings appear in approximately 85% of all biologically active compounds. The nitrogen, oxygen, or sulfur heteroatom modulates electron density, hydrogen bonding, and aqueous solubility. 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 core scaffold in kinase inhibitor design for oncology therapeutics and improved handling characteristics versus the free base form. This compound serves researchers and manufacturers across the pharmaceutical, medicinal chemistry, agrochemical sectors. Whether you require Phenazo Pyridine Hcl 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.
