1344-40-7 Usage
Description
LEAD PHOSPHITE, DIBASIC is a finely ground white crystalline solid that is not soluble in water. It may be toxic by ingestion or skin absorption and can be readily ignited from exposure to heat or external sparks, burning vigorously and persistently.
Uses
Used in Chemical Industry:
LEAD PHOSPHITE, DIBASIC is used as a chemical compound for various applications in the chemical industry, such as a raw material for the production of other lead-based compounds or as an additive in certain chemical processes.
Used in Flame Retardants:
Due to its ability to be readily ignited and burn vigorously, LEAD PHOSPHITE, DIBASIC can be used as a component in the development of flame retardants, which are essential in various industries to prevent the spread of fire and enhance safety.
Used in Research and Development:

It is essential to consider the potential hazards and toxic nature of the compound when considering its applications.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
LEAD PHOSPHITE, DIBASIC is self-reactive. A fiber drum of lead diphosphite caught fire apparently without any external cause. A gradual decomposition appears to have taken place, yielding lead phosphate, water, and phosphine. Phosphine , in turn, is spontaneously flammable in air and was probably the ignition source for the resulting fire [Kirk and Othmer 10:489. 1947]. Reacts violently with hydrogen sulfide [Bretherick 1979. p. 977-978].
Health Hazard
Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
Fire Hazard
Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.
Check Digit Verification of cas no
The CAS Registry Mumber 1344-40-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1344-40:
(6*1)+(5*3)+(4*4)+(3*4)+(2*4)+(1*0)=57
57 % 10 = 7
So 1344-40-7 is a valid CAS Registry Number.
