深红色基RC (CAS No.4274-03-7)
- 中文别名
- 5-氯-2-甲氧基苯胺盐酸盐；2-氨基-4-氯苯甲醚盐酸盐；深红色基RC
- 英文名称
- 5-Chloro-2-methoxyaniline hydrochloride
- 分子式
- C7H9Cl2NO
- 所属类别
- 试剂实验设备
- 物化性质
- 深红色基RC为灰白色至浅灰色粉末，属芳香胺盐酸盐，易溶于水，可溶于乙醇，水溶液呈中性或弱酸性。具有重氮化活性，在酸性条件下可与偶合组分快速偶合生成偶氮染料；遇强氧化剂分解，光照或长时间存放会引起色泽加深。
- 技术参数
- 含量（HPLC）≥98.5% 熔点（分解）≥220℃ 干燥失重≤1.0% 水中不溶物≤0.5% 色光（与标准样品比）近似

Product Name:Deep Red Base RC
English Name:5-Chloro-2-methoxyaniline hydrochloride
CAS No.:4274-03-7
Aliases:5-Chloro-2-methoxyaniline hydrochloride, 2-Amino-4-chloroanisole hydrochloride, Deep Red Base RC
Molecular Formula:C7H9Cl2NO
Physical Properties:Deep Red Base RC is an off-white to light gray powder. It is a hydrochloride salt of aromatic amine, readily soluble in water and moderately soluble in ethanol; its aqueous solution is neutral to weakly acidic. It has diazotization activity and couples rapidly with coupling components under acidic conditions to form azo dyes. It decomposes in the presence of strong oxidants, and prolonged exposure to light may darken its color.
Uses:It is mainly used as a diazo base for ice dyes (insoluble azo dyes) in the dyeing and printing of cotton, linen, viscose and blended textiles. It is also used as an intermediate in the synthesis of azo pigments, pharmaceuticals and organic compounds.
Technical Specifications:
Assay (HPLC) ≥98.5%
Melting point (decomposition) ≥220℃
Loss on drying ≤1.0%
Water insolubles ≤0.5%
Shade: close to standard sample
