Chemical Structure
Description
The occurrence of 1-Chloro-2-nitroethane is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Chloro-2-nitroethane (CAS 625-47-8) is a high-purity analytical reference standard with the molecular formula C2H4ClNO2 and a molecular weight of 109.51 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1-Chloro-2-nitroethane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 109.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1-Chloro-2-nitroethane 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.
