Chemical Structure
Description
(R)-2-chloro-5-(2-hydroxy-1-(methylamino)ethyl)phenol (CAS 1335669-90-3) is a high-purity analytical reference standard with the molecular formula C9H12ClNO2 and a molecular weight of 201.65 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-2-chloro-5-(2-hydroxy-1-(methylamino)ethyl)phenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (R)-2-chloro-5-(2-hydroxy-1-(methylamino)ethyl)phenol 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.
