Monosodium citrate, more correctly, sodium dihydrogen citrate (Latin: natrium citricum acidulatum), is an acid salt of citric acid. Disodium citrate and trisodium citrate are also known. It can be prepared by partial neutralisation of citric acid [3] with an aqueous solution of sodium bicarbonate or carbonate. It has a slightly acidic taste.
It is also used as an anticoagulant for laboratory testing, in that blood samples are collected into sodium citrate-containing tubes for tests such as the PT (INR), APTT, and fibrinogen levels. Sodium citrate is used in medical contexts as an alkalinizing agent in place of sodium bicarbonate, [2] to neutralize excess acid in the blood and urine ...
Sodium citrate/sodium lauryl sulfoacetate/glycerol sold under the brandname Microlax and Micolette Micro enema, among others, is a small tube of liquid gel that is used to treat constipation. [ 1 ] The main active ingredients are sodium lauryl sulfoacetate (0.90% w/v ), sodium citrate (9.0% w/v ) and glycerol .
In 2003, Ööpik et al. showed the use of sodium citrate (0.5 g/kg body weight) improved running performance over 5 km by 30 seconds. [8] Sodium citrate is used to relieve discomfort in urinary-tract infections, such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative.
Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH.
Sodium picosulfate is a prodrug. [5] It has no significant direct physiological effect on the intestine; however, it is metabolised by gut bacteria into the active compound 4,4'-dihydroxydiphenyl-(2-pyridyl)methane (DPM, BHPM).
In the early 1980s, Crest was reformulated to use SMFP, under the trademark "Fluoristat"; today Crest toothpastes use sodium fluoride or stannous fluoride. Compared to straight fluorides, sodium monofluorophosphate has slightly less aftertaste. SMFP is also used in some medications for the treatment of osteoporosis. [2]
Sodium tartrate (Na 2 C 4 H 4 O 6) is a salt used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings. As a food additive, it is known by the E number E335. It is made by the combination reaction of baking soda/Sodium Bicarbonate (NaHCO₃) with tartaric acid.
