921-26-6 - Introduction

Diisopropylphosphoridous DICHLORIDE, chemical formula (C3H7) 2npcl2, is a colorless liquid. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: DIISOPROPYLPHOSPHORAMIDOUS DICHLORIDE is a colorless liquid with a strong pungent odor.
-Solubility: It can be miscible with many organic solvents (such as ethanol, dimethylformamide and dichloromethane, etc.).

Use:
-Synthesis of chlorinated phosphorylene ester compounds: DIISOPROPYLPHOSPHORAMIDOUS DICHLORIDE can be used as a reagent in the reaction for the synthesis of chlorinated phosphorylene Ester and other organic synthetic compounds.
-Organic synthesis: It can be used to prepare compounds such as oxalamine.

Method:
The preparation of DIISOPROPYLPHOSPHORAMIDOUS DICHLORIDE is usually carried out by the following steps:
1. Dimethyl phosphoramidite (DMA) reacts with isopropanol to generate diisopropyl phosphoramidite (DIPA).
2. Reaction of phosphoryl chloride (PCl3) with DIPA to obtain DIISOPROPYLPHOSPHORAMIDOUS DICHLORIDE.

Safety Information:
- DIISOPROPYLPHOSPHORAMIDOUS DICHLORIDE has a pungent odor, so you should avoid inhaling its vapor when using it, and operate in a well-ventilated place when using it.
-It is an organophosphorus compound with certain toxicity and should be used with care to avoid skin contact and swallowing.
-During storage and operation, it is necessary to seal the container to prevent leakage, and avoid contact with oxidants, alkalis, acids and other substances to avoid unsafe chemical reactions.
-carefully read the relevant material safety data sheet (MSDS) before use, and in accordance with the correct method of operation for storage, handling and waste disposal.
