CATO supplies (3R)-3-amino-5-(methylthio)pentanoic acid;hydrochloride (3R)-3-amino-5-(methylthio)valeric acid;hydrochloride (3R)-3-amino-5-methylsulfanyl-pentanoic acid;hydrochloride (3R)-3-amino-5-methylsulfanylpentanoic acid;hydrochloride (3R)-3-azanyl-5-methylsulfanyl-pentanoic acid;hydrochloride 336182-07-1 D-beta-homomethionine-HCl (CAS 336182-07-1), a certified reference material (molecular formula C6H13NO2SHCl, MW 199.69 g/mol) for analytical method development and quality control.
The molecular framework of (3R)-3-amino-5-(methylthio)pentanoic acid;hydrochloride (3R)-3-amino-5-(methylthio)valeric acid;hydrochloride (3R)-3-amino-5-methylsulfanyl-pentanoic acid;hydrochloride (3R)-3-amino-5-methylsulfanylpentanoic acid;hydrochloride (3R)-3-azanyl-5-methylsulfanyl-pentanoic acid;hydrochloride 336182-07-1 D-beta-homomethionine-HCl (C6H13NO2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (3R)-3-amino-5-(methylthio)pentanoic acid;hydrochloride (3R)-3-amino-5-(methylthio)valeric acid;hydrochloride (3R)-3-amino-5-methylsulfanyl-pentanoic acid;hydrochloride (3R)-3-amino-5-methylsulfanylpentanoic acid;hydrochloride (3R)-3-azanyl-5-methylsulfanyl-pentanoic acid;hydrochloride 336182-07-1 D-beta-homomethionine-HCl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
