Chemical Structure

4-(4-Aminophenyl)-3-methyl-4-oxobutanoic acid hydrochloride CAS 120757-13-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Aminophenyl)-3-methyl-4-oxobutanoic acid hydrochloride.

4-(4-Aminophenyl)-3-methyl-4-oxobutanoic acid hydrochloride (CAS 120757-13-3) is a high-purity analytical reference standard with the molecular formula C11H13NO3HCl and a molecular weight of 243.69 g/mol.

The molecular framework of 4-(4-Aminophenyl)-3-methyl-4-oxobutanoic acid hydrochloride (C11H13NO3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 4-(4-Aminophenyl)-3-methyl-4-oxobutanoic acid hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
