Chemical Structure
Description
The occurrence of 2-Chlorooxazole (hydrochloride) is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chlorooxazole (hydrochloride) (CAS 2059937-68-5), molecular formula C3H2ClNOHCl and molecular weight 139.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chlorooxazole (hydrochloride) (C3H2ClNOHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 139.96 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Chlorooxazole (hydrochloride) 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.
